The Geissele Single Stage Precision trigger is relatively light and smooth and breaks very predictably. The reset is very positive and tactile. These triggers make a great drop-in replacement for that old, clunky Mil-Spec trigger found in most AR-15/AR-10 rifles. The SSP and SD-SSP are precision-focused single-stage triggers with the option between Geissele’s flat trigger bow or a standard M4 curved bow. They are precision machined from S7 tool steel which provides excellent impact resistance, strength, and toughness. Geissele triggers are known for their consistent, long-lasting performance.

Which is better? Curved or Flat?
One is not necessarily better than the other. It all comes down to personal preference. Just remember, the best trigger is the one you get out and train with. IYSYS.
